Answer»

Let the C.P = k RS.

PROFIT = 15 % on C.P =&GT; profit = 15k/100

S.P = C.P + profit = k + 15k/100 = 115k/100

=> 115k/100 = 230 => k =230 x (100/115) = 200Rs.

Profit = 15 % on 200 Rs = 30 Rs.

Let the C.P = k Rs.

Profit = 15 % on C.P => profit = 15k/100

S.P = C.P + profit = k + 15k/100 = 115k/100

=> 115k/100 = 230 => k =230 x (100/115) = 200Rs.

Profit = 15 % on 200 Rs = 30 Rs.
